Late in the night, when everyone had gone to bed, a team of four people dressed in similar white invisible suits set out like thieves in the dark for the Chu family mansion in the emperor's courts.
Thanks to T4, who deactivated the security system of the Chu's they managed to scale past the front gates quite easily. Not even the few bodyguards who were monitoring the compound had a clue.
The biggest security flaw of the mansions in the emperor's courts was the short gates at the entrance. Everyone assumed that that they were so safe because the front gates and the entire fence were manned by armed soldiers but an internal threat was something else.
The group of four easily entered the main house with the key card T4 made for her. Most of the lights were off and it looked like everyone had gone to bed, it was coming to midnight after all.
Since a plan had already been made, everyone went to their assigned areas immediately.
